Error filles up the system logfile

I've searched a bunch of mac discussion boards and there are still lot's of people who are having the same error but nobody gives a clear solution to fix this bug. The following error occurs every 20 minutes and filles up the system.log file. As this person (http://discussions.apple.com/thread.jspa?messageID=664892) I do not use the internal Apple Mailserver. I am running MacOS Server 10.4.7 and I guess it's a bug since months. I've also disabled some cronjobs for a number of CMS systems. No changes! On a PM I am having nearly the same setup and the message doesn't pop up which leads me to the conclusion that Apples xserve monitoring software might cause this message.
